Catalytic Activity
ATP + acetate + CoA = AMP + diphosphate + acetyl-CoA.
Enzyme Regulation
Inhibited by acetylation at Lys-642 and activated by deacetylation. {ECO:0000269|PubMed:16788062}.
Function
Important for maintaining normal body temperature during fasting and for energy homeostasis. Essential for energy expenditure under ketogenic conditions (By similarity). Converts acetate to acetyl-CoA so that it can be used for oxidation through the tricarboxylic cycle to produce ATP and CO(2). {ECO:0000250, ECO:0000269|PubMed:16788062}.
Ptm
Reversibly acetylated on Lys-642. The acetyl-CoA synthase activity is inhibited by acetylation and activated by deacetylation. {ECO:0000269|PubMed:16788062, ECO:0000269|PubMed:19608861}.
Sequence Caution
Sequence=BAB55390.1; Type=Erroneous initiation; Evidence={ECO:0000305}; Sequence=BAC03853.1; Type=Frameshift; Positions=250; Evidence={ECO:0000305}; Sequence=BAC03853.1; Type=Miscellaneous discrepancy; Note=Sequencing errors.; Evidence={ECO:0000305};
Similarity
Belongs to the ATP-dependent AMP-binding enzyme family. {ECO:0000305}.
Subcellular Location
Mitochondrion matrix {ECO:0000269|PubMed:16788062}.
Subunit
Interacts with SIRT3. {ECO:0000269|PubMed:19535340}.
